Surveys are a method of data collection for the purpose of analyzing the data into information. The information comes from a group of people but is then generalized to fit a larger population.
A Survey exists in various forms, but the most common is the questionnaire, which can either be in written form or as online forms.
For most people in the information business, a survey is an invaluable source of data and insights. Businesses, academic institutions, media companies, and government agencies can also benefit from surveys significantly.
Four modes of survey data collection are commonly used. They are as follows:
- Telephone survey
- Pencil survey
- Face-to-face survey
- Self-administered paper
- Self-administered computer survey (generally online)
Even though surveys differ widely in how they are carried out and used, they have certain components that are common.
These common components have been confirmed after detailed studies by survey methodologists, statisticians, psychologists, and other experts in the field of research.
